Kev tsim kho tshuaj ua si lub luag haujlwm tseem ceeb hauv ntau qhov xwm txheej tseem ceeb, ntu ntu xws li txheej txheej, pob zeb, cov ntaub ntawv thermal rwb thaiv tsev, thiab kev tsim dej tsis zoo. Los ntawm kev txhim kho cov ntaub ntawv kev ua tau zoo, txhawb kev tsim kho kom zoo, thiab txuas ntxiv kev pabcuam lub neej ntawm cov qauv, lawv tau dhau los ua qhov tseem ceeb ntawm "unsung heroes" ntawm niaj hnub architecture.
Daim ntawv thov hauv Architectural Coatings
Kev tsim kho tshuaj ua kom muaj txiaj ntsig zoo rau ob qho tib si kev ua haujlwm thiab ib puag ncig profile ntawm txheej txheej:
Titanium Dioxide (TiO₂) ua haujlwm ua cov xim dawb, muab cov opacity siab thiab ci ntsa iab thaum tib lub sijhawm txhawb cov txheej txheej huab cua tiv thaiv thiab txuas ntxiv lub neej kev pabcuam ntawm sab nrauv tiav.
Acrylic Resins ua thawj zaj duab xis- tsim cov tshuaj hauv cov xim latex; boasting qhov zoo xws li muaj zog adhesion thiab eco-cov dej phooj ywg-raws li formulations (VOCs tsawg), lawv tau dav siv nyob rau hauv sab nrauv phab ntsa xim, rooj tog zaum, thiab automotive topcoats.
Nano-silica txhim kho cov txheej txheej adhesion, txhuam tsis kam, thiab huab cua; los ntawm kev tsim ib qho peb -sib nqus network qauv, nws ua tau zoo txhim kho cov neeg kho tshuab lub zog ntawm cov xim zaj duab xis.
Hydroxyethyl Cellulose (HEC) ua haujlwm ua cov thickener, dej-retention agent, film- qub, thiab pigment dispersant; nws tiv thaiv sagging thaum lub sij hawm daim ntawv thov thiab txhim kho ob qho tib si kev ncaj ncees ntawm cov xim qhuav zaj duab xis thiab cov khoom cia ruaj khov.
Precipitated Calcium Carbonate ua haujlwm ua haujlwm ntxiv, txhawb cov xim zaj duab xis qhov kev puas tsuaj, kev cuam tshuam, thiab adhesion thaum tiv thaiv kev tawg thiab chalking; nws yog dav siv nyob rau hauv ob qho tib si sab hauv thiab sab nrauv latex xim.
Magnesium Hydroxide yog ua hauj lwm los txo VOC cov ntsiab lus -yog li txhim kho cov txheej txheej ib puag ncig tus phooj ywg-thaum ib txhij txhim kho nws cov khoom ntim thiab daim ntawv thov smoothness.
Admixtures hauv pob zeb thiab Cement Systems
Kev tsim kho tshuaj ua raws li "functional regulators" hauv kev sib xyaw ua ke:
Diethanolamine accelerates kev txhim kho thaum ntxov -stage cement lub zog, txo cov cua sov tsim thaum lub sij hawm hydration, thiab retards lub sij hawm teem; qhov no yuav pab tiv thaiv cov pob zeb tawg thiab ua kom zoo dua qub thaum tsim kho.
Sodium Gluconate ua haujlwm raws li kev tiv thaiv kev tiv thaiv, tswj kev teeb tsa tus nqi ntawm cov pob zeb ua ke-ib qho tshwj xeeb muaj txiaj ntsig hauv qhov chaw siab - qhov kub thiab txias los yog cov xwm txheej cuam tshuam nrog kev thauj mus los ntev -.
Graphene, thaum muab tso rau hauv pob zeb, ua rau nws muaj zog compressive, tiv thaiv chloride ion nkag mus, thiab tag nrho cov kav ntev. Nws qhov tshwj xeeb "bridging effect" inhibits tawg propagation, ua rau nws yog ib qho zoo tagnrho additive rau tej yaam num uas yuav tsum tau nruj durability, xws li txuas hniav thiab subway lem. Cellulose ethers (xws li HPMC) tau siv dav hauv mortars, putty hmoov, thiab cov nplais nplaum nplaum los txhim kho cov dej tuav thiab kev nplaum, tiv thaiv hollowing thiab detachment, thiab txhim kho kev tsim kho.
Functional Additives hauv Thermal Insulation thiab Fireproofing Materials
Polyurethane nplaim taws retardants (xws li TCPP thiab TDCPP) yog ib qho tseem ceeb additives rau rigid polyurethane foams, ua kom lawv ua tau raws li B1- qib nplaim-retardancy tus qauv. Cov additives no feem ntau siv rau sab nrauv phab ntsa rwb thaiv tsev boards, ru tsev rwb thaiv tsev txheej, thiab txias cia cov ntaub ntawv siv tshuaj tsuag, zoo sib npaug ob qho tib si thermal rwb thaiv tsev thiab hluav taws kub kev ruaj ntseg.
